MC44BS374CA Technical data
High Speed I2C Compatible Bus
After the chip address, two or four data bytes may be received.
If three data bytes are received, the third one is ignored.
If five or more data bytes are received, the fifth and following ones are ignored, and the last ACK
pulse is sent at the end of the fourth data byte.
The first and third data bytes contain a function bit, which lets the IC distinguish between frequency
information and control information. If the function bit is a logic 1, the two following bytes contain control
information. The first data byte after the chip address, may be byte CO or byte FM. The two bytes of
frequency information are preceded by a logic 0.
16.6 I2C Read Mode Format
The chip address (I2C) is:
The incoming information consists of the read mode chip address byte. The device then answers with an
ACK followed by one byte containing three bits of status information. No acknowledge is answered by the
modulator after this byte.
STA = Start condition
CA = Chip Address
FM = Frequency information, high order bits
FL = Frequency information, low order bits
C1 = Control information, high order bits
CO = Control information, low order bits
STO = Stop condition

1 1 0 0 1 0 1 1 (ACK) = $CB (hex) in read mode
